Trying to block all ports due to security I got everything working other then the dns doesn't resolve at all.

New set of rules here as well. I added the blocking rules as last match. I have tried to add DNS but it just stated DNS can't respond.

Hi all, I have the following problem:
My LAN is 192.168.1.1/24 with DHCP pool 192.168.1.10-254 and sub network of 192.168.50.1/24 with DHCP Pool 192.168.50.2-254. I want to block my login page on the 192.168.50.1/24 subnet. OPNsense system by default allows it on both networks. I tried a firewall rule blocking just the 192.168.1.1 but I'm faced with the DHCP Server stops registering IP's on that subnet. What would you guys suggest to just block the opnsense login interface without losing the DHCP Server set. I tried to block all traffic and just pull dhcp and dns and it pulls the dhcp but won't pass the dns server. I have a firewall with block rules. Tried first and last rules and when my block rules are as last rules it seems to pass it all along even if I remove the Allow All Network out.
